EVA foam products above can be added to protect the cover material, such as cotton, breathable felt. Utility protection EVA EVA foam material is to ensure that in the period before the end of the molding, the molding temperature can be maintained EVA foam desired. In the deflection pattern to be machined is small, mold design should be simple. EVA foam products mold heat requirements are not tall, the use of wood, polyester or natural resin ring oxygen glass molds made of steel or sufficient. Forming member can be causative vacuum, vacuum-molded plastic or female, the male mold is completed. In order to be able to protect the EVA material in the case of small resistance in the case of a mold to extend security film edge MUST have a larger arc. EVA foam to reduce the temperature quickly, both sides of the same temperature reduction requirements, to avoid rebound, deformation. Once a good member forming temperature reduced to less 80 ℃, it can be extracted from the mold.
EVA also known as EVA foam, EVA material can also do fire EVA products, anti-static EVA products, EVA high-frequency products, environmental protection odorless EVA products, widely used in IT, electronics, appliances, hardware, electronics, glass products, precision spectrograph and other packaging products. EVA foam products flexible, lightweight, good density, rich elastic energy as a buffer material to protect the product and better learn from spreading external impact force, back in pads to be attached to the product appearance from the shock anti-friction effect. Meanwhile, EVA material with insulation, moisture resistance, corrosion resistance and a series of excellent properties causative.
Since the fine quality EVA foam products, EVA foam products Earthquake lower specific heat capacity, EVA material appearance because a large cut gap acts as a cooling channel, EVA foam to reduce the appearance of temperature quickly, rarely able to maintain heat . It needs to be for foam insulation boards, avoid the EVA foam taken from the oven or a hot plate, the temperature quickly reduced, shall meet the requirements of the temperature hot forming processes.
EVA foam before thermoforming sure to handle EVA foam drying purposes, hooks stickers thermoformed EVA material requires the purposes of heating, the heating process can be implemented in an oven, a hot plate or infrared heater. The duration of heating may be based on the sheet thickness (about 1mm / min).
EVA foam commonly used colors are black or white, color EVA EVA foam materials are rubber material, usually red, yellow, blue, pink, orange, green, gray, brown and other, arbitrary colors can be produced.
